The gain frequency can be also written using Pr.125 (instruction code: H99) or Pr.126 (instruction code: H9A).
NOTE
• Set 65520 (HFFF0) as a parameter value "8888" and 65535 (HFFFF) as "9999".
• For the instruction codes HFF, HEC, and HF3, their values once written are held, but cleared to zero when an inverter reset
or all clear is performed.

H9696: Inverter reset
As the inverter is reset at the start of communication by the computer, the
inverter cannot send reply data back to the computer.
HFD
H9966: Inverter reset
When data is sent normally, ACK is returned to the computer, and then the
inverter is reset.
HF4
H9696: Batch clearing of fault records
All parameters return to initial values.
Whether to clear communication parameters or not can be selected
according to the data.
• Parameter clear
H9696: Communication parameters are cleared.
H5A5A: Communication parameters are not cleared.
• All parameter clear
H9966: Communication parameters are cleared.
HFC
H55AA: Communication parameters are not cleared.
For the details of whether or not to clear parameters, refer to
When a clear is performed with H9696 or H9966, communication related
parameter settings also return to the initial values. When resuming the
operation, set the parameters again.
Performing a clear will clear the instruction code HEC, HF3, and HFF
settings.
Only H9966 and H55AA (all parameter clear) are valid during the password
